These are Sapphires! They are 3.5mm Sapphire rondelles that show the variety of color that sapphires have...white to middle blue to deep blue. They are beautiful and almost need no explanation. I like to wear this strand alone and just let the necklace do the talking.
It measures 27 inches long, but can be worn anywhere up to 30 inches long with the sterling silver links in the back. Because of the length, it can be worn long or doubled, depending on your mood. Of course, if you want to pair it with something else, you can wear it with most anything, like the alternate image shows (other necklaces sold separately). Every girl needs some sapphires!
